UNSPSC 31171711: Ring gears

UNSPSC 31171711 Ring gears is a Commodity code that in recent state and local solicitations covers industrial transmission components—primarily taper-bushed reducer gearboxes and associated bushings—for water and wastewater treatment facilities. The Hillsborough County Board of County Commissioners' May 2026 ITQ for two Dodge Torque-Arm II speed reducers and four taper bushing kits ($30,400 budgeted) demonstrates the code's application to replacement of worn or failed drive components in operational water systems where exact part compatibility is critical and no substitutes are accepted. State and local water utilities dominate the issuing-body mix, with water treatment and reclamation authorities in Florida and Georgia driving recent activity; county-level departments of water resources and infrastructure represent the primary buyer class.

Recent activity concentrates in Georgia and Florida, with Hillsborough County and Gwinnett County Board of Commissioners posting procurement notices within the last four months. The Hillsborough County ITQ (due May 8, 2026) called for delivery to the Northwest Water Reclamation Facility in Tampa within 30 days of purchase order issuance, with strict delivery-window requirements and no loading-dock capability on site. The Gwinnett County IFB (due May 8, 2026) for particle counter replacement at water filter plants, while nominally outside the ring-gear scope, illustrates the broader water-treatment equipment replacement cycle driving procurement in the region. No other recent state or local opportunities under this code appear in the record; the category shows sparse activity overall, concentrated in water and wastewater operations where drive-component reliability directly affects system continuity.
